Desmos is an online service that allows you to create graphs using a function formula. The function itself fits into the left column, and the graph is automatically plotted on the right side. The service will be useful to those who need to quickly and simply build a function graph, for whom the graphing of functions causes difficulties or to those who need to check the correctness of plotting with the least cost.

In addition to the fact that Desmos Calculator can perform all the functions of conventional graphing calculators, it also has several additional features that conventional graphing calculators do not have.

What you can do in DC:
